Evaluation Kit for the MAX14915

Please check latest availability status for a specific part variant.


The MAX14915 evaluation kit (EV kit) provides a proven design to evaluate the MAX14915, octal high-side switch with extended diagnostics. The EV kit includes the MAX14915 evaluation board and a graphical user interface (GUI) that provides communication from a PC to the target device through a USB port and the USB2GPIO interface board. The USB2GPIO EV kit should be ordered separately.

The GUI is compatible with Windows 10 for exercising the features of the MAX14915 IC. The EV kit GUI allows individually controlling of eight high-side switches through the high-speed SPI interface and receive a diagnostic information from the MAX14915, including open-wire/ open-load conditions, state of the output channels, multiple undervoltage alarms, global and per channel overtemperature alarms, and multiple fault alarms.

The MAX14915 EV kit must be powered from an external +24V power supply and can consume more than 10A when fully loaded. The USB2GPIO interface board is powered from the USB port.

The MAX14915 EV kit board comes with a MAX14915AFM+ installed in a 48-pin, 6 x 6mm FC2QFN package.
